Product Description

Product name: Photoinitiator 944

Cas No.: 70624-18-9

Molecular formula: (C35H66N8)n=4-5

Molecular weight: 708.34

Molecular-weight: 2000-3100

Photoinitiator 944 is white to yellowish particles, its ordorless, flash point is high than 150℃. Photoinitiator 944 is readily soluble in organic solvents such as chloroform, ethyl acetate, and n-hexane; slightly soluble in methanol; but insoluble in water. Its solubility characteristics facilitate dispersion within non-polar polymers..

Photoinitiator 944 is frequently used in conjunction with UV-327 and UV-531 to absorb ultraviolet energy, thereby preventing materials from absorbing excessive ultraviolet radiation and becoming excited.
